Whats the biggest tires I can put on my stock '04 2500 4x4? The 17's are just too small for this truck.

 

I have heard quiet a few guys and/or gals putting on 315/70R17 with no rubbing on 1500's. I would assume (and we ll know what happens when we do that) that with the higher suspension they should fit fine. Also being a 2500 you have the luck of having a solid axle and the A-arm issue rubbing in nil. The companies are starting to put out 20" off-road tires since the popularity of the Dodge 20" rims. If you give me the tire size you have now i have a lil spreadsheet that calcs the overall height. And then you can go from there.

 

Thanks RAM, Right now im running the Factory tires 17x8 or 265/70-17.

 

Actually let me clarify what you have.

Your wheels (rims) are 17x8
Your tires are 265/70R17, about 31" tall.

I have read that 315/70R17 will fit fine on the 2500 4x4's.

Keep in mind that some shops might give you a hard time about changing tires since the 2500 comes with Load rating E tires. I believe BFG makes an AT tire in the size 315/70R17's with an E load rating.

My 2500 4x4 CTD came with Michilin(sp) on-off road tires. Not the best off road, but I've heard reports they last 70k+ miles. I'll be keeping them for a while because it's nice to drive a stock truck some times (I have 2 lifted/modified vehciles that I tow with my Ram).

Good Luck,
Sam

 

Those are the same as I have on mine. They are 31.61" tall.
The 20" tires that come optional are 275/60/20 and they are 32.99"
The 315/70/17 are 34.36"

Here is the formula ((((width*(ratio/100)/25.4)*2)+rim))
((((275*(70/100)/25.4)*2)+17))

 

Thanks Guys, Im gonna check out the 315/70/17's and see if they will work.

 

Ihave a question for anyoe who might know the answer. I havea v6 dodge ram with flowmasters, throttle body spacer, kn intake and running 285 75 16's can i go to a 315 or is that going to hurt my engine or trany.

 

Just to let ya know the 285's are 32.83" as the 315's are 34.36" Just need a speedo correction.

 

Its just that several people have told me that i will losa a lot of power and might have transmition problems. But like you are saying its only a matter of inches. What do u think bro. I think i want to go with thorn birds for the looks, im running bfg mudders no but want a more aggresive look. Im getting a 3inch body this week and i have a 2inch coil spring spacer kit and add a leafs on it now, think i can fit 35's
and finnaly how do u set up a pic on here?????????

 

I posted to your post on how to upload pics.
